Computer use may be a risk factor for glaucoma, according to recent research from Japan.
Dr Masayuki Tatemichi from Tokyo's Toho University studied the connection between computer use and visual problems on a group of more than 10,000 Japanese workers.
The study found that there was a relationship between computer use and refractive errors (near and farsightedness). Further, there was a higher rate (nearly double) of glaucoma in heavy computer users with refractive errors.
Glaucoma is an eye disease that manifests symptoms of visual disruption and headaches and can lead to blindness.
